I've done this and continue to run a couple products on Amazon. I funnel all of my profits back into bizdev, including trademarks & patents, trying different advertising platforms, new product development, qa tools for my products, etc. I've done strictly private label so far, but there are some wholesaler price lists that I have which are intriguing. If nothing else it's been a good way to teach myself marketing, imports, and more about IP law...I hope to do a hardware startup in future, which would likely involve Shenzhen manufacturing, so learning to find and interact with Chinese factories has also been valuable.
